Hi,
I want to recommend you to use the ticketing system for specific cases. This way we will be able to privately discuss the exact case and provide you with a workaround for it.
In addition, I want to recommend setting the AutoScaleMode to DPI when using custom scaling.
You can check the following article as well: https://docs.telerik.com/devtools/winforms/knowledge-base/hdpi-tips-and-tricks

Thank you! As for the first check for null, I was wrong.
But the main problem is that:
1. Behavior with the standard DPI and with the custom DPI is different, and unexpected events occur that do not occur with the standard DPI.
2. Even if you setup 101% of the DPI, the interface elements "leave", and the difference is not 1%.
3. In my case #2 (above) on custom DPI we receive "null reference exception", but on 100% DPI exception will not be occured.

Thank you for sharing this with us.
Please, note that we have a check for the null:
if (this.Owner != null && this.Owner.Pages.Count > 1) this count > 0
We will investigate the second point in details and I will update this item.
